PREFACE The standard specifications included in this Circular are intended to assist members in the buying and selling of their materials and products. These specifications are derived from many sectors of the metals, paper stock, plastics, glass, and electronics industries and are constructed to represent the quality or composition of the materials bought and sold in the industry. The specifications are internationally accepted and are used throughout the world to trade the various commodities. Parties to a transaction may specify particular variations or additions to these specifications as are suited for their specific transactions and for their individual convenience. Any deviation from the standard specifications, how- ever, should be mutually agreed to and so stipulated in writing by the par- ties to the transactions. ISRI maintains an Arbitration Service as a means of enabling members to settle differences between themselves or between one of them and a non- member. In addition, the “Guidelines for Metals Transactions” contain supplementary information that will aid members in completing their business transactions. It is recommended that these Guidelines be reviewed and that members use them in conjunction with the actual specifications in the conduct of their business. ISRI’s Scrap Specifications Circular is posted in PDF format at least once per year on the ISRI web site. To ensure you have the most up-to-date version, visit ISRI.org/specs.
